Review Quiz

1. What are the global and local aspects of DNS architecture?

2. What is an alias record?

3. What are three types of records that can be added using Server Admin to Mac OS X

Server’s DNS zone files?

4. What are three possible steps you can take when investigating a DNS problem?

Answers

1. DNS is a distributed system. It is local in that each separate domain is responsible for

its own configuration, so that domain configuration files are located on multiple DNS

servers across the Internet. It is global in that all the separate domains are integrated

into one unified system in which queries are handled by the responsible name server

and all clients can obtain correct name resolution from anywhere on the Internet.

2. Canonical name (CNAME): Stores the “real name” of a server when given a nick-

name or alias. For example, mail.pretendco.com might have a canonical name of

mailsrvr1.pretendco.com. A CNAME record is created for each entry in the Alias

field when adding a machine to a zone.

3. Alias (CNAME), machine (A), and service (SRV) records.

4. You can:

a. Verify network settings.

b. Use Network Utility to test for forward and reverse lookups.

c. Use Network Utility to ping the DNS server.

Use Network Utility to test for basic IP connectivity by pinging another device on

the subnet.
